GMAT Math Cheat Sheet: 5 Essential GMAT Math Formulas You Must Know in 2024

Individuals intending to sit for the GMAT exam in 2024 must be familiar with the essential math formulas. These formulas must be at your fingertips and you should know when and how to use them. That said, here are the top 5 essential GMAT math formulas to help you crack the quantitative section of the standardised test in 2024. Have a look. 

The GMAT quantitative section assesses your problem-solving abilities and understanding of fundamental mathematical concepts. While a fancy calculator might seem tempting, true mastery lies in leveraging a strong foundation in core formulas. Here, we explore the top 10 essential formulas you must know to conquer the GMAT math section in 2024:

• Arithmetic: Average (Mean): Σx_i / n (Sigma x subscript i all divided by n), where Σ represents sum, x_i represents individual values, and n represents the total number of values. Weighted Average: (Σw_i x_i) / Σw_i, where w_i represents the weight assigned to each value (x_i).
• Algebra: Linear Equation: Ax + By = C, where A, B, and C are constants and x and y are variables. Percent Change: [(New Value – Old Value) / Old Value] x 100%.
• Geometry: Area of a Rectangle: Length x Width, Area of a Triangle: (1/2) Base x Height, Pythagorean Theorem (Right Triangles): a^2 + b^2 = c^2, where a and b represent the legs of the triangle and c represents the hypotenuse.
• Probability: Probability of Event A: Favorable Outcomes for A / Total Possible Outcomes. Probability of Event A happening THEN Event B (Independent Events): Probability(A) x Probability(B).
• Permutations & Combinations (Counting): Permutation (Order Matters): nPr = n! / (n – r)! (n factorial divided by (n minus r) factorial), where n is the total number of items and r is the number of items selected. Combination (Order Doesn’t Matter): nCr = n! / (r! x (n – r)!), where n and r are defined as above.

Common Math Concepts to Help You Ace the GMAT Exam 

GMAT Math Cheat Sheet: One cannot expect to ace the GMAT quantitative section without having a stronghold on their rudimentary math concepts. While the GMAT doesn’t require advanced mathematics, a solid understanding of core principles is crucial for success. Here are some common math concepts that will serve as a strong foundation for conquering the GMAT’s quantitative section:

• Arithmetic: This forms the bedrock of the GMAT’s quantitative section. You’ll need a firm grasp of operations like addition, subtraction, multiplication, and division, along with the ability to manipulate fractions, decimals, and percentages confidently. Additionally, concepts like ratios, proportions, and working with exponents and roots are frequently tested.
• Algebra: Algebraic concepts play a significant role in translating word problems into mathematical equations. Brushing up on your skills in solving linear and quadratic equations, manipulating inequalities, and working with functions will be highly beneficial. Understanding how to isolate variables and perform algebraic operations efficiently is key to solving numerous GMAT problems.
• Geometry: While not as heavily emphasized as arithmetic and algebra, a basic understanding of geometric shapes, their properties, and area and volume formulas is essential. Familiarity with concepts like lines, angles, triangles, rectangles, circles, and basic 3D shapes like cubes and cylinders will be advantageous.
• Data Analysis: The ability to interpret and analyze data is a valuable skill tested on the GMAT. Understanding concepts like mean, median, mode, and standard deviation will equip you to solve problems involving data sets and probability distributions.
• Problem-Solving Strategies: The GMAT emphasizes critical thinking and problem-solving approaches. Techniques like estimation, elimination of answer choices, and backsolving can be powerful tools in tackling GMAT problems efficiently.

GMAT Math Mistakes to Avoid in 2024

The quantitative section of the GMAT, while seemingly straightforward for some test-takers, can present a significant hurdle. This is because this section is prone to errors, which can lead to a decline in your overall score. To maximise their performance, test-takers must approach the GMAT quantitative section with caution and be aware of the common pitfalls.

Refer to the common mistakes outlined below to bolster your chances of securing better scores in the GMAT. 

• Misinterpreting the Question: Careful reading and comprehension are paramount. Ensure you grasp the crux of the question before attempting to solve it. Rushing through or making assumptions can lead to selecting incorrect answer choices.
• Calculation Errors: While calculators are permitted, a strong foundation in arithmetic is crucial. Proficiency in performing calculations accurately and efficiently is essential to avoid careless mistakes.
• Unit Errors: Pay close attention to the units used in the question and answer choices. Inconsistency in units can lead to incorrect solutions, particularly in problems involving rates, conversions, or percentages.
• Overlooking Assumptions: The GMAT often relies on implicit assumptions within the problem itself. Being mindful of these assumptions and ensuring your solution aligns with them is crucial to avoiding errors.
• Neglecting Time Management: The GMAT quantitative section is timed. Develop a strategic approach to pace yourself effectively and avoid spending an excessive amount of time on any single question.

How to Prepare for GMAT Quantitative in Less than 30 Days? 

While a month may appear short for GMAT math preparation, significant improvement is achievable with focused effort and a well-defined strategy. Here’s a breakdown of how to optimize your GMAT math preparation within this timeframe:

Week	Tasks
Week 1	Dedicate 4-6 hours per week to GMAT math. Divide time into daily or every-other-day sessions of 45-90 minutes. Allocate at least half the time to focus on weaker areas. Practice mixed problems to replicate the GMAT format. Integrate full-length practice tests every weekend. Time yourself strictly and simulate test-day conditions. Analyze performance thoroughly after each test.
Week 2	Focus on solidifying understanding of core GMAT math concepts. Sharpen skills in algebra: solving linear equations, understanding linear functions, etc. Hone ability in problem-solving and data analysis: ratios, percentages, data interpretation, etc. Be prepared for questions on quadratic expressions, probability, etc.
Week 3	Focus on solidifying understanding of core GMAT math concepts. Sharpen skills in algebra: solving linear equations, understanding linear functions, etc. Hone ability in problem-solving and data analysis: ratios, percentages, data interpretation, etc.Be prepared for questions on quadratic expressions, probability, etc.
Week 4	Take a GMAT practice test from the Official Guide or a reputable prep company. Analyze performance to identify strengths and weaknesses. Tailor study plans effectively.
